|---|---|
| blast/o | germ or bud |
| chrom/o,chromat/o | color |
| chyl/o | juice |
| hem/o,hemat/o | blood |
| immun/o | immune, resistant |
| lymph/o | clear fluid |
| morph/o | form |
| myel/o | bone marrow or spinal cord |
| phag/o | eat or swallow |
| plas/o | formation |
| reticul/o | a net |
| thromb/o | a clot |
| blood | circulating tissue of the body consisting of fluid with formed elements (red blood cells, white blood cells, and platelets) suspended in the fluid |
| plasma | liquid portion of the blood and lymph; contains water, proteins, and cellular components (i.e., white blood cells, red blood cells, and platelets) |
| serum | liquid portion of the blood that remains after clotting |
| neutrophil | a granular leukocyte, named for the neutral stain of its granules that fights infection by swallowing bacteria (phagocytosis) (neutr= neither) (phil=attraction for); Normal Range (in stained blood smear): 54-75% |
| polymorphonuclear (PMN) leukocyte | another term for neutrophil, referring to the many segments in its nucleus (poly= many; morpho=form; nucleus= kernel) |
| lymph | fluid that is circulated through the lymph vessels |
| lymph capillaries | microscopic vessels that draw lymph from tissues to the lymph vessels |
| lymph vessels | vessels that receive lymph from the lymph capillaries and circulate it to the lymph nodes; also called lymphatic vessels |
| lacteals | specialized lymph vessels in the small intestine that absorb fat into the bloodstream (lacteus=milky) |
| chyle | white or pale yellow substance in lymph that contains fatty substances absorbed by the lacteals |
| passive immunity | a short-lasting immunity that results from foreign antibodies that are conveyed either naturally, through the placenta to a fetus, or artificially, by injection of a serum containing antibodies |
| active immunity | a long-lasting immunity that results from stimulating the body to produce its own antibodies; developed either naturally, in response to an infection, or artificially, in response to the administration of a vaccine |
| poikilocytosis | presence of large, irregularly shaped red blood cells (poikilo= irregular) |
| reticulocytosis | an increased number of immature erythrocytes in the blood |
| erythropenia | an abnormally reduced number of red blood cells |
| immunosuppression | impaired ability to provide an immune response |
| lymphadenopathy | enlarged (diseased) lymph nodes |
| splenomegaly | enlargement of the spleen |
| red cell morphology | as part of identifying and counting the white blood cells, the condition, size, and shape of red blood cells in the background of the smeared slide are noted |
| differential count | determination of the number of each type of white blood cell (leukocyte) in a stained blood smear; each type is counted and reported as a percentage of the total examined |
